About this tool
Merge multiple .xlsx files into a single workbook, deduplicating sheet names — all in your browser.
Excel Merge combines two or more Excel workbooks into a single .xlsx file. Every sheet from every uploaded workbook is preserved in the merged output, with duplicate sheet names automatically suffixed (e.g. Sales (1)) so nothing is overwritten.
It is the quick answer to consolidating monthly reports, combining data from multiple teams, or joining workbooks before further processing. The merge runs entirely in your browser, so confidential spreadsheets never transit a server.
